GKAM<br />

Assembles modal mass, damping and stiffness matrices<br />

LFREQ Input-real-no default. Lower frequency limit of modes to use in modal<br />

transformation.<br />

HFREQ Input-real-no default. Upper frequency limit of modes to use in modal<br />

transformation.<br />

UNUSED5 Input-integer-no default. Unused.<br />

UNUSED6 Input-integer-no default. Unused.<br />

UNUSED7 Input-integer-no default. Unused.<br />

NONCUP Output-integer-no default. If K2DD, B2DD, and M2DD are purged.<br />

then the model is considered uncoupled and NONCUP is set to -1.<br />

FMODE Output-integer-default=1. The lowest mode number resulting from<br />

LMODES or LFREQ and HFREQ.<br />

KDAMP Input-integer-default=1. Viscous modal to structural damping flag. If<br />

set to -1, then viscous modal damping (SDAMPING Case Control<br />

command) will be included in the stiffness matrix as structural<br />

damping.<br />

FLUID Input-logical-default=FALSE. Fluid damping processing flag. If TRUE,<br />

then the modal damping set identification number is obtained from<br />

the SDAMPING(FLUID) Case Control command.<br />

UNUSED12 Input-logical-default=FALSE. Unused.<br />

Remarks:<br />

1. USETD may be purged if there are no extra points (NOUE0.<br />

8. See the <strong>NX</strong> <strong>Nastran</strong> Reference Manual for further details.<br />
